It's almost always worth spending the time to either fix all warnings or, after determining it's a false positive, suppressing it with a #pragma. Once things are relatively clean, it's easy to see if new code/changes trip a warning. Often unexpected warnings are a sign of subtle bugs or at least use of undefined behaviors. Sorting those out when they come up is a heck of a lot easier than tracing a bug report back to the same warming.
